This guide explains what applies to hardware suppliers.

This means hazard categories, pictograms, and SDS formats are largely harmonized with the EU CLP Regulation and the US OSHA HazCom 2012 standard — reducing the duplication burden for global suppliers. However, Canadian WHMIS has specific bilingual requirements and some classification differences that require careful attention. ### Hazardous Product Classification Categories WHMIS 2015 defines two main hazard groups: Physical Hazards (e.g., flammable liquids, compressed gases, oxidizing solids, self-reactive substances) and Health Hazards (e.g., acute toxicity, skin corrosion, respiratory or skin sensitization, carcinogenicity, reproductive toxicity). For hardware products, the most commonly triggered categories include: lithium battery electrolytes (flammable liquids), solders and fluxes (acute toxicity, skin sensitization), thermal interface compounds, and adhesives. Determine whether your product — or its constituent materials sold in bulk — qualifies as a hazardous product under these categories. ### SDS Requirements (16-Section Format) Suppliers of hazardous products sold to Canadian workplaces must provide a Safety Data Sheet (SDS) in the standardized 16-section GHS format. The 16 sections cover: identification, hazard identification, composition, first-aid measures, fire-fighting measures, accidental release, handling and storage, exposure controls/PPE, physical and chemical properties, stability and reactivity, toxicological information, ecological information, disposal, transport, regulatory information, and other information. The SDS must be in both English and French for supply into Canada. Health Canada administers SDS requirements under the Hazardous Products Regulations. ### WHMIS Supplier Label Requirements A WHMIS supplier label must appear on any hazardous product supplied to a Canadian workplace. Required elements include: product identifier, supplier identifier and Canadian address, hazard pictograms (GHS-style), signal word (Danger or Warning), hazard statements, precautionary statements, and any supplemental label elements. The label must be in both English and French — either as a bilingual single label or two separate language labels. Labels must be durable, legible, and prominently displayed. Downstream employers may add workplace labels for decanted or transferred quantities. ## WHMIS compliance process 01 Classify each product component under WHMIS 2015 hazard categories. Review Safety Data Sheets from your raw material suppliers and apply the classification rules in the Hazardous Products Regulations. If a component is a mixture, use the mixture classification rules (concentration-based cut-off values) to determine whether the finished product is itself a hazardous product. 02 Prepare a 16-section SDS in both English and French for each classified hazardous product you supply to Canadian workplaces. The SDS must reflect Canadian regulatory references (including Canadian exposure limits such as OELs from occupational health regulations), not simply a reposted EU or US SDS. Retain a copy and make it available to customers. 03 Create a compliant WHMIS supplier label in English and French. Include all required GHS elements: product identifier, supplier name and Canadian address, appropriate hazard pictograms, signal word, hazard statements, and precautionary statements. Ensure the label is sized appropriately for the container and is durable under expected storage conditions. 04 Ensure downstream workplace labels meet employer obligations. Employers who decant hazardous products into unlabelled containers must apply a workplace label. Your SDS and training materials should support your customers' employer obligations under provincial occupational health and safety legislation that incorporates WHMIS. 05 Update the SDS and label when significant new data emerges — for example, new toxicological findings, changes to ingredient hazard classification, or revised Canadian exposure limits. WHMIS does not prescribe a fixed review interval, but three-year periodic reviews are common practice and align with Health Canada guidance. ## Frequently asked questions ### Does WHMIS apply to finished consumer products or only to workplace chemicals? WHMIS applies to hazardous products supplied for use in Canadian workplaces — it is a workplace safety framework, not a consumer product safety law. Consumer products (items sold retail for non-occupational household use) are generally excluded from WHMIS labelling and SDS requirements. However, the same product can be subject to WHMIS when supplied to a business purchasing it for workplace use (e.g., a cleaning chemical sold retail is consumer product, but the same bulk product sold to a building services contractor is subject to WHMIS). For hardware, if your product contains hazardous chemicals and is sold to manufacturers, assemblers, or industrial customers, WHMIS applies even if an identical SKU is also sold retail. ### Which electronics components commonly trigger WHMIS classification? The most common WHMIS-triggering components in electronics include: lithium-ion battery electrolytes (flammable liquids, acute toxicity); solder wire and solder paste containing lead or flux activators (reproductive toxicity, acute toxicity, skin sensitization); thermal pastes and interface compounds containing silicone oils or metal particles; conformal coating chemicals (flammable liquids, skin irritants); and cleaning solvents such as isopropyl alcohol. Assembled, enclosed finished products (e.g., a shipped smartphone or router) are typically exempt from WHMIS SDS requirements as consumer products, but the component chemicals used during manufacturing are not. ### Must the SDS be in both English and French? Yes. The Hazardous Products Regulations require the SDS to be in both English and French when supplied to a workplace in Canada. This applies nationally — it is not limited to Quebec. The bilingual requirement reflects Canada's Official Languages Act obligations. You may provide a single bilingual document or two separate unilingual documents; both approaches are compliant. Supplying only an English-language SDS is non-compliant under federal WHMIS legislation, regardless of which province the customer is in. ### How does WHMIS 2015 differ from the old WHMIS 1988? WHMIS 1988 used Canada-specific hazard symbols (a distinct set of hatched border pictograms), the Material Safety Data Sheet (MSDS) format, and a classification system developed independently of international frameworks. WHMIS 2015 replaced all of this with GHS-aligned hazard categories, the standardized 16-section SDS format, and GHS pictograms (the red-bordered diamond symbols). Practically, this means MSDS documents are no longer acceptable — only compliant SDS documents are. The hazard pictograms on supplier labels must be GHS pictograms, not the old WHMIS symbols. Products classified and labelled under WHMIS 1988 must have been updated to WHMIS 2015 — the transition period ended in 2018. **Disclaimer:** Educational resource only.
